A friend at work recommended this specific product to improve my immune system. I travel by commercial air, live half my life in hotels, and have to shake hands with thousands of people each year at trade shows. I was getting two or three bad respiratory infections each year and was getting worse with age. I've made six major shows since I started on this product and haven't even had a cold. My wife, who also seems to have had some immune weakness, has also been cold free. So far, we really like this stuff.

This is my first order of this product, so can't give a definitive answer, other than it appears to be a quality, cost effective form of CoQ10.
Please get involved in fighting the FDA's effort to take away our rights to buy and use the supplements we choose. Google "stop the fake food safety and vitamin safety bill S510.
iHerb's selection, price, and service, is the best.

I don't have a genuinely objective way to measure the results of using this product now for a month and an half, except to say I feel fine, and think my energy level and over all sense of well being couldn't be better. As well, I've been able to stop taking so many supplements, so I'm also saving money. This was my second jar, and I ordered the woman's version of this product for my wife. Our third order is on the way now. Thanks.

I stirred this package into my 7 a.m. cup of coffee, turning it into a "mocha" drink. Aside from the nutrition available, the stuff completely killed my appetite and kept me alert through my morning meetings. I may use this as my replacement for my 10 o'clock Red Bull; a move that I'm certain will improve my overall health.
